The feed chute and feed ram may be selectively positionable at one of several angular positions with respect to the rotary cutter. In this manner, the force applied by the feed ram on the workpiece is a function of the weight of the feed ram and the angular position of the feed ram with respect to the rotary cutter. Full Article
c Shredding machine By www.freepatentsonline.com Published On :: Tue, 14 Apr 2015 08:00:00 EDT A machine for shredding plastic container including a pressing device having a main housing having an interior space, a first opening for feeding container and a second opening for disposing the shredded pieces, a fixed plate position at one end within the housing and having slits arranged in matrix pattern, facing the interior of the housing, and having sharp edges, a movable plate having plurality of blades connected to at least one arm. The movable plate can move along a central axis within the housing and the blades have edges facing the sharp edges of the fixed plate. The containers are placed between the plates, such that when the movable plates moves along the central axis of the housing toward the fixed plate, the blades crash and cut the container into flakes. Pegs protrude from the blades, such that when the arm moves forward, the pegs punch the container. Full Article
c Method for producing a confectionery semi-processed product, such as a chocolate-type product By www.freepatentsonline.com Published On :: Tue, 14 Apr 2015 08:00:00 EDT A method of producing a semifinished confectionary product, such as chocolate or similar, using at least one centrifugal unit for simultaneously grinding and mixing at least some of the ingredients of the semifinished product, and which includes an elongated processing chamber with a substantially horizontal axis, at least one inlet for the ingredients to be processed and one outlet for the processed ingredients, and a powered shaft fitted inside the processing chamber, coaxially with the axis, and fitted with a succession of radial appendixes arranged between the inlet and the outlet; the method including the steps of loading at least a first ingredient of the semifinished product through the inlet; grinding the first ingredient inside the grinding and mixing unit by rotating the shaft at a first speed; loading at least a second ingredient through the inlet, after grinding; rotating the shaft at a second speed to grind and mix the ingredients to form a mixture of the same grain size as the semifinished product; loading at least a third ingredient through the inlet; mixing the third ingredient with the previously ground mixture to form a further mixture; bringing the further mixture to a given temperature to obtain the semifinished product; and transferring the semifinished product to a storage or packaging station.

c Organic shredder apparatus and method for operating an organic shredder By www.freepatentsonline.com Published On :: Tue, 21 Apr 2015 08:00:00 EDT An apparatus and method is provided for organic material reduction and preparation for subsequent recycling or disposal in a self-contained system which is safe for equipment operators, and highly cost and floor-space efficient. The apparatus includes a preferably-shaped hopper for receiving organic materials to the reduced, preferably a floating auger, a solids pump and a macerator. The system preferably generates a processed organic material discharge with a particle size on the order of ⅛″ without concern as to the liquid content of the incoming organic material. The apparatus may be operated by a method which is completely automated following operator initiation, including automatically attempting self-clearing actions in the event of detecting clogs or jams in the processing components.
